Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is actually a method wherein a substrate is subjected to a number of volatile precursors, which respond and/or decompose to the substrate area to supply the desired skinny movie.
Actions within the CVD Process:
Precursor introduction
Chemical response and film development
By-merchandise removal
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is an additional spelling generally used exterior The us, particularly in British English. Regardless of the spelling variation, it refers to the similar substantial-precision coating procedure.
five. CVD and PVD Coating
CVD and PVD coating are the two Actual physical vapor deposition approaches used for making use of slender movies. Nonetheless, they vary substantially of their processes and apps.
CVD (Chemical Vapor Deposition):
Utilizes chemical reactions
Commonly requires bigger temperatures
Ideal for manufacturing coatings with superb conformality
PVD (Bodily Vapor Deposition):
Uses physical procedures like sputtering or evaporation
Frequently operates at reduce temperatures
Suited to attractive coatings and thin films
